I am a girl who enjoys her birthday. I’ve never wanted a big party, but I like the feeling of having family or a few close friends get together to share a special day with you, and I definitely like that my birthday means funfetti cake and ice cream. When I thought about how best to celebrate Brett’s birthday in the low-key way that we both prefer, I tried to figure out what the equivalent of my beloved funfetti might be for him. The answer? Taking him to Big Daddy’s, a decades-themed diner on the Upper East Side that serves tuna melts and tater tots, burgers and shakes, and keeps it easy for the gluten free girl who wants to enjoy her burger on her boyfriend’s birthday.
